Vitamin K2's time to shine has come—move over vitamin D! Once only known for its role as a "koagulation" factor in blood clotting, vitamin K2 is emerging as another fundamental anti-aging nutrient. While vitamins D and E have garnered the majority of interest in the last decade, the impact of vitamin K2 on aging bones and hearts demands that we give it equal attention. Whereas most vitamin and mineral supplements use vitamin K in its form of K1 (phylloquinone sourced from plants) because it is easily available and cheap, it is the natural form of K2 (menaquinone sourced from friendly bacteria) that is the most biologically active and shown to enhance both bone formation and vascular health. The full compilation of recent research underscores the idea that K1 and K2 should be appreciated as separate nutrients with distinct physiological actions and benefits. K1 is the more familiar vitamin known for its key role in directing blood-clotting in the body and the one given as ...

Unfortunately, getting older comes with a common consequence affecting up to 16 percent of elderly people – gradual reduction in brain size, which is associated with problems in learning and memory. However, a new study reports that daily supplementation with high doses of B vitamins may help slow the rate of brain degeneration. Oxford researchers gave 168 individuals over the age of 70 supplements containing high doses of folic acid (0.8 milligrams per day), B6 (20 milligrams per day) and B12 (0.5 milligrams per day), or a placebo as part of a randomized, double-blind controlled trial. Then, following two years of the supplementation program, the participants’ brains were assessed using serial volumetric magnetic resonance imaging scans. The researchers reported their results in the September issue of PLoS One: the rate of brain shrinkage, or atrophy, in the group taking the supplements was 53 percent lower in comparison to the group taking the placebo. Their conclusion was that the h...

Boron's ability to induce sex hormone levels give it a role preventing chronic disease. For example, adequate dietary boron may potentially reduce risk of lung cancer (1). The effects also explain why boron supplementation may support bone density guarding against osteoporosis (2). However, caution should be exercised before supplementation with boron. Greater estrogen levels due to boron supplementation may potentially increase risk of breast cancer (1;2). Thus, boron should not be taken by women with high risk of breast cancer or who've had breast cancer.

Nickel is a known carcinogen. When in the diet in toxic amounts it contributes to oxidative stress, just as mercury and cadmium do, by reducing glutathione thereby interfering with cell membrane integrity and increasing lipid peroxidation (1). The oxidative damage, like from free iron or copper, can cause DNA damage (2). Reference List 1. Valko M, Morris H, Cronin MT. Metals, toxicity and oxidative stress.

As one travels around the world, especially in developing countries, the state of oral health stands out as an issue that needs attention. Fluoride treatment of drinking water can be an important step in improving oral health (1), but some populations may find it's not necessary because they may already be consuming adequate or even too much fluoride daily. Careful review of fluoride exposure must be evaluated region by region before deciding to treat local water with fluoride (2). According to the World Health Organization (WHO), flouride intake can vary depending fluoride already in water, on diet and other variables such as local pollution (2). Areas of greater volcanic activity, for example, tend have highest concentrations of fluoride in groundwater (2). The act of tea drinking can provide significant amounts of fluoride (1). In parts of China where high-fluoride coal is burned, the ash that pollutes crops may be providing fluoride (2). And in Tanzania, the use of contaminated...

A young electrician with a painful gouty arthritis in 2005 became the first case observed of occupational exposure of toxic amounts of molybdenum (1). Molybdenum is an activator of xanthine oxidase, which oxidizes xanthine producing uric acid (2). Too much produced hyperuricemia (1). The electrician can be thankful that his doctors found the cause of the gout because of previous men afflicted with gout by having consumed 10 to 15 mg of molybdenum daily (3;4). Tolerable uptake limits are set at 2 mg (2). Reference List 1. Selden AI, Berg NP, Soderbergh A, Bergstrom BE. Occupational molybdenum exposure and a gouty electrician.

Toxicity of manganese is more common than its deficiency (1), which unfortunately cause damage to the brain. Manganese appears to cause neurogeneration by activating microglia and causing them to release neurotoxins such as reactive oxygen and nitrogen species, which produce oxidative damage (2). The neurotoxins are also thought to possibly alter influence of neurotransmitters such as dopamine or gamma-aminobutyric acid (GABA) (1). According to a studies on non-human primates exposed to high doses of manganese, the mineral can lead to deficits in working memory performance and even induce an increase of beta-amyloid production linking manganese to Alzheimer's disease (3;4).

Vanadyl ions can act in an insulin-like manner in the body. Thus, when taken orally they may potentiate insulin’s effects, which can potentially improve situations of type 2 diabetes (1). Bioavailability of vanadyl compounds, however, can depend on whether of organic or inorganic nature (2). The organic bis-ligand oxovanadium appear to be far more bioavailable and efficacious than inorganic vanadyl sulfate (2). According to a couple of trials performed earlier this year in Canada, the organic version taken in doses of 10-90mg has no adverse effects (2). Further, it was found to help reduce fasting blood glucose levels and improves glucose tolerance (2). Reference List 1. Conconi MT, DeCarlo E, Vigolo S et al.

As Gropper, Smitth and Groff tell it, arsenic "conjures an image of toxicity" unlike any other ultratrace mineral (1), but there are good things that come of arsenic and its story is worth discussion. Without arsenic, DNA synthesis couldn't happen. This is because arsenic is needed for normal metabolism. Specifically, the mineral is required for forming and using methyl groups to S-adenosylmethionine (SAM) (1). SAM is used for methylation to form DNA compounds (1). Arsenic, in fact, may have once been part of DNA itself. The mineral is very similar to phosphorus, which is currently the backbone of nucleic acids. Because this is is so it has been suggested that arsenic may have served as an alternate element early on, although not possible in modern biochemistry (3). According to scientists Felisa Wolfe-Simon, Paul Davies and Ariel Anbar, there may even be possibility that organisms may still be using arsenic in their DNA today, but simply not yet found (3).

Because of chromium’s known ability to potentiate action of insulin, an adequate chromium status is important especially for people with diabetes, insulin resistance and hypoglycemia to maintain glycemic control (1;2). According to an evaluation of 15 randomized clinical trials, amounts of about 200 mcg per day appear to improve use of glucose (3). In addition, a placebo-controlled trial of 180 Chinese patients found that doses at 200 mcg and as high as 1,000 mcg of chromium taken per day lowered blood glucose levels by 15-19% (3). Dose may depend on form of chromium since one form may be more bioavailable than another. Chromium picolinate appears to be the most bioavailable and, thus, the most potent (3). The amount of chromium taken, however, should not exceed 1,000 mcg per day due to potential toxicity (1). Chromium picolinate, in addition, should not be taken in amounts over 600 mcg because of association with renal failure and hepatic dysfunction (1). Reference List 1. Groppe...

Advertisements that suggest chromium picolinate may help consumers lose fat or gain muscle mass are largely overstated. A double-blind, randomized, placebo-controlled 12-week trial in 2001 found that chromium picolinate offered moderately obese women participating in an exercise program no significant changes to body composition, resting metabolic rate, plasma glucose, serum insulin, plasma glucagon, serum C-peptide or serum lipid concentrations (1). The 2001 study’s results supported at least three previous studies of which had also shown that chromium picolinate had been ineffective in changing body composition in obese women, in military personnel and in weight-lifting football players (2-4). A 12-week randomized, placebo-controlled trial in 2008 combined chromium picolinate with conjugated linoleic acid and evaluated effects on body composition changes of young, overweight women for 12 weeks (5).; still, no significant changes were found (5). Lastly, because of chromium’s known eff...

Prostate cancer has been associated with low serum selenium concentration. To investigate the mechanisms by which selenium affects gene expression prostate tissue, researchers set out to measure activity of glutathione peroxidase in men with relatively high serum selenium concentration (1). The researchers measured serum selenium concentration in 98 men using atomic absorption spectrometry. Afterward, 12 men were selected for having the highest serum selenium concentration and another 12 were identified as having the lowest serum selenium concentration. Fresh prostate tissue samples were taken of the selected men to measure selenium concentration and glutathione peroxidase activity. The study, which was published in July 2007, reported a positive correlation found between a higher serum selenium concentration and a prostate tissue concentration. However, there was no significant increase of glutathione peroxidase activity associated with the higher concentration of selenium concentrati...

Humans contain about 2-4g iron of which most is in hemoglobin and to a lesser extent myoglobin. Iron from diet is found in heme (animal foods) and nonheme (plant foods) forms. The heme iron needs to be hydrolyzed where as the nonheme is enzymatically freed. Heme iron is absorbed intact accross the brushborder of the enterocyte whereas nonheme iron is released as ferric in the stomach, which may be reduced to ferrous. The ferric is absorbed across brush border by binding to transporters and the ferrous facilitated by chelators and membrane proteins.Chelators inhibit or enhance absorption of iron. Absorption is also regulated by hepcidin and ferroportin. Other iron-absorption enhancers are sugars, acids, animal meat, and mucin. Other inhibitors are polyphenols, oxalates, phytates, phosvitin and some minerals.Iron is stored in the liver, bone marrow and spleen. Uptake into tissues depends on transferrin. Iron needs depend on its loss such as through menstrual losses and dietary intake. De...

A mineral supplement I've taken in the past includes 10mg zinc and 1mg of copper. Thus, the amount of zinc is not at the "higher than 50mg" level that can cause a copper deficiency because of interference with bioavailability (1). This is exactly the 10:1 ratio as suggested to avoid any copper deficiency (2). Someone did his/her homework. 1. http://lpi.oregonstate.edu/infocenter/minerals/zinc/ 2. http://www.pccnaturalmarkets.com/health/2934002/

Purpose of study: Zinc and copper are lost in significant amounts in acute diarrhea and zinc has been suggested as a therapy for its possible facilitation of water and electrolyte transport across intestinal mucosa to prevent villous atrophy and modulate immune response. This study evaluated whether or not zinc and copper supplementation had any beneficial effect on acute watery or bloody diarrhea when given with standard treatment. Type of study: Randomized, double-blinded placebo-controlled trial Method used to conduct study: Children ages 6-59 months with acute diarrhea were given standard treatment and randomized to placebo, zinc only (Zn 20mg/5ml elemental zinc), or zinc and copper (2mg/5ml of elemental copper) together via syrup. There were 808 children chosen for the study out of 1,200 screened over the period of Aug 2003 and Oct 2006. Each provided more than three stool samples in prior 24 hours, who had duration of diarrhea for up to 72 hours and who were able to orally acce...

As iron deficiency develops gradually without anemia, symptoms can appear that can include pallor and problems of behavior, cognition, learning and attention span. These can particularly manifest themselves in children. Adults may witness problems related to work performance and productivity. The effects may be related to impairment of the neurotransmitter gamma-aminobutyric acid (GABA) used to inhibit dopamine production in the brain and/or immune system impairment leading to more susceptibility to infection and inability to keep a normal body temperature. The first stages of iron deficiency result in diminished liver, spleen and bone marrow iron stores and decreased plasma ferritin. Second stages begin when stores are low and iron transport decreases. Transferrin saturation decreases, which increases total iron-binding capacity, and there is limited iron for function in hemoglobin. This leads to a rise in protoporphyrin, the precursor to heme in hemoglobin. Finally, the anemia occurs...

Hemochromatosis is a genetic disorder caused by one of several mutations related to double-than-normal iron absorption, which increases susceptibility to iron overload (1). Although the disorder affects about one in 200 in the U.S., it’s still largely unrecognized and can lead to deposits in organs—such as the liver—leading to organ damage and failure if not treated early enough (2-4). Because the disorder is most prevalent in males of Northern European ancestry, particularly Celtic (5), it was hypothesized as recently as 2007 to be a possible Neolithic adaptation (6). The Neolithic period marked an early European dietary transition from high intake of meat to cereal grains (6). Whether or not this hypothesis is correct, the state of the disorder suggests potential dietary management through eating primarily vegetarian foods such as the one eaten during the time of these early ancestors—cereal grains, little red meat, and limited vitamin C intake. This low-iron diet to prevent to iron...
